Effect of the Additive Amount of Nano Carbon Black on Thermal Insulating Performance of Vacuum Insulation Panel

摘要：

　　Vacuum insulation panels (VIPs) with both high efficiency in thermal insulation and long lifetime were desired in their engineering design and application.Core material is the kernel part of VIPs and greatly influences the thermal insulating performance of VIPs.In this paper,1%,3%,5% and 10% of NCB was evenly blended with fumed silica,chopped polyester fibers,and titanium dioxide powder to form the hybrid core materials (HCM) for VIPs.The influence of the additive amount of NCB on the microstructure,BET specific surface area and thermal conductivity of the as-prepared VIPs was investigated.In order to achieve the optimal thermal insulating performance with low thermal conductivity and long service life,the additive amount of NCB should be 3%.
